EDUARD EULENSTEIN, OF LEIPZIG, GERMANY.

COPYING-PRESS.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed April l. 1907. Serial No. 365,780.

To all whom it may concern:

Be it known that I, EDUARD EULENsTEIN, a subject of the King ot" Saxony, residing at Leipzig, in Germany, have invented a certain new and useful Copying-Press, of which the following is a specification.

This invention relates to an arrangement for use in Connection with writing desks to allow of dispensing with a separate letter-copying press and permit of locking up the letter-book while it is compressed.

A construction embodying the invention is. illustrated in the annexed drawing, in which Figure l is a side-view, partly in section, Fig. 2 a partial sectionalside-view on a larger scale, Fig. 3 a partial plan-view, Fig. 4 a front-view partly in section, and Fig. 5 a sectional side-view of the open press.

The copying apparatus comprises a drawer arranged in a part of the desk occupied in ordinary desks by a drawer, for example under the central part of the desk. The letter-book is placed in4 this drawer and is automatically compressed when the latter is closed, and the press-plate is automatically removed from the book when the drawer is opened. In the drawer-space below the table a bars b o angle-iron are fixed to serve as bearings for rollers d. The axes of the lower' group of rollers d are in a horizontal plane, whereas the axes of the upper rollers are in a plane downwardly inclined towards the rear of the desk. The lower press-plate f rests upon the lower rollers d and is xed to a plate g adapted to close the front of the drawer-space and provided in the usual manner with a handle and lock. For greater rigidity the drawer may also be provided with a rear-wall and side-walls. To the plate f is fixed a transverse wall or partition h which supports the hinges ofthe upper press-plate 1c. Between the walls g and h there is sufficient space vfor the insertion of the letter-book. The wall h has at its upper part recesses n for the hinges m of the plate lc. The cross-section of the plate c tapers towards the rear so that its upper surface is in a plane parallel with the plane containing the axes of the upper rollers d, so that when the drawer is pushed in the upper rollers simultaneously abut against the said plate and cause uniform pressure to be applied to the letter-book o. The latter must, of course, be of the proper thickness, or if it is too thin suitable distance-pieces must be placed under or over I it so that the desired pressure is secured when the drawer is pushed in. Means are also provided for automatically lifting the upper press-plate when the drawer is opened. The lower press-plate is of suHicient length to enable it to be pulled out a considerable distance without tilting downwards. Above the upper rollers d an iron bar p is fixed to the under-surface of the table a, and a rod 7' is connected to this bar by supports q and is slidable on the under-surface thereof. To the iront end oi' the rod r is hinged a hook s. The plate c has near its rear edge a recess t across which is xed a rod u. During the pulling out oi' the drawer the hook s slides on the upper surface oi the plate lc until it enters the recess t and engages the rod it. During the continued outward movement of the drawer the hook moves with the plate lc until the support qabuts against a stop, so that the rod r can move no farther forward. The hook thereupon causes the press-plate c to rotate on its hinges supported by the wall h. The letterbook is thus exposed and can be removed.

The insertion and withdrawal of the drawer-press are very easy, and there is no risk of the drawer becoming jammed, since owing to the inclined position of the upper rollers d and the corresponding surface ot the upper press-plate, pressure is not applied until the last stage ot the insertion, and is removed at the beginning of the withdrawal.

What I claim as my invention and desire to secure by Letters Patent of the United States is:`

1. A copying press comprising in combination a drawer' and drawer casing, two press-plates the outer surfaces of which converge towards the rear in said drawer and movable therewith and two stationaryseries of rollers in the casing, said rollers being in planes converging with the same angle as the press-plates 2. A copying press comprising in combination a drawer and drawer casing, means comprising a hinged pressure plate for applying' pressure to a book in the drawer, and means whereby the press-plate is automatically lifted from the book when the drawer is opened.

A copying press comprisingl in combination a drawer and drawer casing', means comprising' a hinged pressure plate for applying' pressure to a book in the drawer, and means whereby the press-plate is automatically lifted from the book when the drawer is opened said means consisting' of a hook connected t0 the casing above the press, said hook having limited movement in a direction parallel to the drawer.

In witness whereof I have signed this specification in the presence of two witnesses. i
